Custom section dividers - using CSS chevrons

Hello SS.

see: https://www.nerv.co.uk

I've added some custom CSS chevrons to the end and beginning of sections as follows:

This is an example of the code I am using:

section[data-section-id="6411cfe88e268e5653a774b3"] {
  ::before {
    -webkit-box-sizing: content-box;
    -moz-box-sizing: content-box;
    box-sizing: content-box;
    width: 50%;
    height: 100%;
    position: absolute;
    content: "";
    bottom: 1.2em;
    left: 0;
    background: #EAECE7;
    -webkit-transform: skewY(4deg);
    transform: skewY(4deg);
}
   &:after {
    -webkit-box-sizing: content-box;
    -moz-box-sizing: content-box;
    box-sizing: content-box;
    width: 50%;
    height: 100%;
    position: absolute;
    content: "";
    bottom: 1.2em;
    right: 0;
    background: #EAECE7;
    -webkit-transform: skewY(-4deg);
    transform: skewY(-4deg);
}
}

It's fine on mobile and when the desktop browser is 'standard' width, but as you can see when the browser is stretched wider, the chevron breaks and the 'sharp' point in the middle is lost.

Any smart folks out there able to help me fix this?

Many thanks.

I can not see the problem on your site. Can you mark your issues on your images?

Thanks for coming back on this.

On this one you can see the chevron breaks in the centre:

And on this one you can see where the outside edges of the chevron don't overlap the block below and there is a crack of white instead of a solid background.

@Beyondspace Any thoughts on this?
